HAND-OPERATED DRIVING MECHANISM.

Application filed June 5, 1911.

To all whom it may concern:

Be it known that I, WILLIAM H. GEORGE, citizen of the United States of America, and resident of Dexter, Dallas county, Iowa, have invented a new and useful Hand Operated Driving Mechanism, of which the following is a specification.

The object of this invention is to provide an improved construction for a hand motor which may be employed in operating a washing machine or other device.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which Figure 1 is a side elevation showing my improvement applied to a washing machine. Fig. 2 is a plan of the same. Fig. 3 is an elevation of parts of the device at right angles to Fig. 1.

In the construction of the machine as shown the numeral 10 designates a suitable support such as the tub of a washing machine. A bracket 11 is fixed to and projects horizontally from the lower portion of the support 10 and a hand lever 12 is fulcrumed near its lower end on and is arranged verticallv relative to said bracket. The hand lever preferably is made of metal and is provided with a removable handle 13 on its upper end. which handle preferably is made of wood. The longer portion of the lever 12, including the handle 13, is above the fulcrum 11. A bracket 14 is fixed to and projects laterally from the support 10 in a plane above the bracket 11 and a lever 15 is fulcrumed intermediate of its ends to said bracket 14. The bracket 14 is of less length than the bracket 11 and the fulcrum point of the lever 12 is at a greater distance from the support 10 than is the fulcrum point of the lever 15. The lower end portions of the levers 12 and 15 are connected by a bolt 16, said bolt extending through the lever 12 and playing loosely in a slot 17 in the lever 15. A pitman 18 is pivoted at One end to the upper end portion of the lever 15 and is adapted to engage a device to be driven such as a pinion 19. In this instance the pinion 19 is mounted on and adapted to turn rotatively an agitator or dolly within the tub.

medium of the lever 12 and handle 13 is considerably more than equal.

In practical operation the lever 12 is oscillated manually and effects an oscillation of the lever 15 and consequent reciprocation of the pitman 18. The pitman 18 acts upon and operates the device or mechanism to be driven, which is adapted to do the work provided for it. The bolt 16 seated in the lever 12 and playing loosely in the slot 17 of the lever 15 is adapted for pivotal connection of'the levers in such manner as to permit movement of the lower extremities thereof through different arcs.

I claim as my invention- 1. A hand operated driving mechanism comprising a suitable support, a rocking lever fulcrumed intermediate of its ends on said support, a device to be driven, power transmitting means connected to one end of the rocking lever and connected in driving relation to the part to be driven, a handlever fulcrumed intermediate its ends on said support substantially parallel to said rocking lever, and a connection between the free end of the rocking lever and one end of the hand-lever so that as the hand-lever is actuated the rocking lever is oscillated about its fulcrum and motion is transmitted to the power transmitting means.

2. A hand operated driving mechanism comprising a suitable support, a hand-lever fulcrumed intermediate its ends to said support, an intermediate lever fulcrumed intermediate of its ends to the support and arranged for oscillation in a path parallel to the swinging path of the hand-lever, power transmitting means connected in driving relation to the part to be driven, and a pivotal connection between the free ends of the hand-lever and intermediate lever.

Signed by me at Des Moines, Iowa, this 2" day of January, 1911.

WILLIAM H. GEORGE.
